chines, of which lthe following is a specifica tion.

This invention relates to vacuum cleaning machines, has particularreference' to animproved dust receptacle and bag therefor, and has foran object to provide a construction adapted particularly tohand-operated port able machines from which the accumulated' dust andlint may be .easily removed.

More specifically, the object ofthis'invention is to provide adustreceptacle witha dust tube leading from the suction-head and openinginto the receptacle and dust bag in such a manner as'not to obstructVAthe interior thereof. This arrangement admits of v ready access to thebag through'out its entire length forthe removal of the dust and lint.

Furthermore, this novel construction prevents the dust and lint fromcollecting about the inner end of lthe dusttube such as occurs in priorstructures Where difficulty has been 'l l experiencedvin dislodging thedust andlint.

Another object of 'the invention'is to provide within the dustreceptacle a peculiar mounting for. the bag, whereby thesameu may beplaced under tension, and the tension be regulated to maintain the bagin distended or stretched position to take advantage of the entirecubical area of the bag the best results.

A further object is tov providea dust receptacle and bag which taper`frm end to end so that dust and lint may bqeasily removed by hand, orby gravity in'itilting 'the dust receptacle. l; I Other objects andadvantages of this ini vention Will be brought out in the followingdetailed description of the present preferred embodiment of theinvention, the same being illustrated in the accompanying drawing,wherein- Figure l is a lside elevation of the vacuum cleaning machineembodying the features of this invention. Fig. 2 is an enlargedlongitudinal section thereof taken vertically through the centralportion of the machine. Fig. 3 is a detail rear end elevation of theldust receptacle and'bag, the cap being removed frein the receptacle,and Fig. 4 is a transverse section through the dust receptacle on theline 4 4 of Fig. 2, looking`tcward the front end of the receptacle.

Referring to this drawing, wherein like parts are designated by similarcharacters of reference2 l0 designates the body of the machine which. inthe present instance cour prises 'the dust receptacle. Mounted on top ofthe dust receptacle is a pair of bellows il of the-usual type havin themovable leaves thereof secured to aree ring plate l2 for al ternatelyoperating the'beliows. The rocking-plate 12 is actuated by any suitablepit-4 man connection 13 connected to the support lngvtraction wheels 14mounted .upc/n` the forward end of the body l0. shown in the presentdrawing, the wheels /14 are mounted upon an axle l5 heid in brackets, 16projecting from the forward end of the body 10. The rear end of the body10 is support. d by handle 17 adapted to be grasped in the [mnd for thepurpose of moving 'the ma- -hine over the surface 'to be cleansed. 'Itis thus seen that when the machine is moved he supporting Wheels llirotate andthrough he pitrnan connection 13 rock the plate 12 nd thusactuate the bellows il to produce a practically constant suction throughthe ody 10. The body l0 or dust receptacle extends preferably throughoutthe entire length of lthe machine and tapers from its rear end toitsforward end. The rear or enlarged en'd is openL and is adapted to beclosed by a cap'18 upon which the handle 17 is mounted, the cap beingheld to the receptacle by -thumb screws 19, or other suitabie'detachthesame having a formation corresponding to the inner walls of thereceptacle 10 and being adapted to support the forward end of the vdustbag @I2-in open position. The dust bag 22Atapers to its opposite end toicorrespond to the shape of the body 10 and is secured at its inner endto a block 23 conforming to the shape of the inner end of the dustreceptacle and adapted to hold the bag in distended position. A threadedbolt 24, or the like, is mounted in the block 23 and extends forwardlytherefrom through the head or clsed end 25 of the dust receptacle. Theout 2G .is threaded upon the outer l dust bag 22. The frame 21 is oi'ring -form, Y

vbnd of the bolt 24 and bears against the-'head 2,5 to Vdrawi the block-23 forwardly and fstret'ch the dust bag 22 and`hold it in .suchstretched. position.

The machine isprovided at' its forwardl end with a forwardly projectingsuctionhead 27 ,of any.' approved form whichmay be supported upon theaxle 15 as shown in Fig. 2, and which communicates with a dust tube 28leading` into the body 10. The dust tubel 28 is pretlerably locatedbeneath the .body 10 at its. forwardb reduced end and eX- ,-"t'endslongitudinally beneath the body to apoint approximately intermediate theends ofthe dust receptacle. The tube 28 is gradually flattened-from itsforward vto its rear end, the flattened end ofthe tube-entering thereceptacle 10, 'extending for a short distance within the receptacle andlying close receptace, owing toits tapering form is i 4v,practica lyunobstructed throughout its enagainst the inner wall ofthe same/ii Asthe tube 28 is ii'attencd, and as it .lies close against the inner wallof the receptacle, the

'tire len th. The tube 28 also passes into the l. -fside no the dust bag22, thelatter having an opening'adaptcd to receive the tube 28.

As shown in Figs/2 and 4 of the drawing,

I the bottom'of the body v,orfreceptacle l0 is arched upwardly as Aat29""a't'- the portion where the dust tube 28 venters the receptacle.,This ,arched f Wgr 4end of` the receptacle .fn-operatie assuction iscreated through e, Oithe dust and the like from being cleaned passesthrough the suction'liead 27 into the dust tube 2Q,

and from the dust vtube into the dust bag 22. As the body l0 is held. ina'tilted position as shown in Fig. 1,"the dust andp lint A from thetube28 fall into the bottom of the 'y dust bag, while theair from thetube 28 v'iis drawn olf by the bellows 11 through the .sides of thedust-'bag 22. lVhen it is dei siredto remove the dust and lint from themachine,l the cap 18 is removed from the I rear `enlarged end of thereceptacle, and

l ,the-.liandmay be readily inserted with-in the open end of the bag 22to withdraw the dust and lint collected therein. Owing .to the taperingform of the bag and the receptacle, Vthe accumulations *within the bagmay be 'readily removed, and if the rece tacle is tilted rearwardly thedust and lint falls out of the bag as there are no shoulders orprojections tending to retain the dust therein. Further, as the bolt 24draws the bag `sol and holds it in stretched position, there are nocreases in the bag to retain the dust and as' the sides of the bag aretaut the dust will not adhere to the bag toany appreciable eX- tent.

changes may be made in the construction of 'end ofthe saine vtoward saidend.
